Once again, mark appeared with ex-girlfriend Amanda, who he still lives with - this time to prove he had never cheated on her

In his first stint on the Jeremy Kyle Show, Mark had taken a DNA test to prove that his son with girlfriend Amanda was really his.

And today Mark was back with a vengeance, to take a lie detector test and prove he hadn't been cheating with now ex-girlfriend Amanda, who he still lives with.

When asked why he wanted to prove he wasn't a cheat, Mark said: "At the end of the day, other people are telling me this, other people are saying that I've done this. It's making me look like a f*****g idiot."

Jez fired back: "Why is that making you look like that? You look like that anyway."

But it was Mark's womanising ways which really caused a stir among viewers, after Jeremy told how Mark had described himself as "the ultimate ladies' man."

Mark denied putting it like that, saying: "Listen, I don't think I'm a ladies' man. I've got the gift of the gab."
